INKING DEVICE FOR RUBBER-STAMP PADS.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application led October 14, 1904. Serial No. 228,396.

Tov @ZZ whom,` it may concern,.-

Be it known'that I, JAMES S. TRIMBLE, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and' -useful Improvements in Inking Devices for Rubber-Stamp Pads, .of which the following is a specification.

My invention relates to devices for applying ink to the surface of a stamp-pad; and the object of the invention is to provide a receptacle for the ink which can be conveniently held in the hand during the operation of inking the pad and from which receptacle the ink will flow with sufiicient freedom to allow the operator to apply it in a thin uniform sheet over the surface of the pad.

A further object is to provide an ink-receptacle by means of which the operator can ink the pad without danger of smearing too much ink in one place and not enough in another or spilling the ink on the fingers or clothes.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in providing a tubular receptacle hermetically sealed at one end and having a porous material in the other end, through which the ink oozes upon the surface of the pad, between which material and the interior of the receptacle a perforated disk is placed.

Further, the invention consists in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a longitudinal-sectional view of an inking-tube embodying my invention. Fig. 2 is an end View with the cap removed. Fig. 3 is a sectional view of the top of the tube, showing the construction of the same. Eig. 4 is a detail of theperforate disk.

In the drawings, 2 represents a tubular receptacle, preferably of metal, of suitable size, having a bottom 3, which after the tube has been filled with ink is brazed or soldered in place, hermetically sealing that end of the tube. The opposite end of the tube is open and provided with an eXteriorly-threaded ring or sleeve 4, secured on the end of the tube and provided at its outer end with an inwardlyturned iiange or lip 5. Within this sleeve is a threaded cap 6, having its top provided with a series of perforations 7 The cap fits snugly within the sleeve 4, and between the top of the cap and the iiange 5 a layer of felt 8 or similar material is provided, covering the perforations 7. A thin cloth material 9 is placed over the felt, and when the cap 6 is forced into the sleeve the flange 5 will engage the edges of the cloth 9 and press it down outside the edges of the felt and hold it firmly between the walls of the cap and sleeve. The felt material will be compressed between the top of the cap and the flange 5, and a tight joint will be formed at this point, preventing any possibility of the escape of the ink from thetube through the joint between the cap and sleeve. The ink, however, will flow through the perforations 7 into the felt and from thence work out through the cloth material, where it can be conveniently spread on the surface of the stamp-pad.

To cover the end of the tube and to protect it from dust and dirt and prevent theink from working out when the device is not in use, I provide a threaded cap 10, having a closed top 11, beneath which is a disk 12, of suitable iiexible material, such as rubber. Vhen the cap l0 is screwed down on the end of the tube, the rubber disk l2 will bear on the cloth material, keeping it clean and free from dust and preventing the ink from working out of the tube into the cap, from whence it would run out on the hands of the person using the device when the cap is removed.

I claim as my inventionl. An inking device for stamp-pads comprising a receptacle closed at one end and open at the other, and having an inwardlyturned iiange at its open end, a cap fitting within said open end and having a series of perforations in its top, a felt, or similar material, provided over said perforations and a cover of pervious material arranged over said felt, and having its edges gripped and held between said cap and flange, substantially as described.

2. An inking device for stamp-pads comprising a tube closed at one end and open at the other and adapted to contain a supply of ink, a perforated plate iitting within the open end of said tube and communicating with the ink therein, and a pervious material fitting over said perforations and secured between said plate and the walls of said tube, substantially as described.

3. An inking device for stamp-pads, comprising a tube closed at one end and open at the other and adapted to contain ink, a threaded sleeve secured to the open end of said cured to the open end of said tube and having at its outer end an inwardly-extending flange or lip, a screwthreaded cap fitting within said sleeve and having a series of perforations in its top, a felt material provided over said perforations, athin cloth disk litting over said felt and having its edges gripped and held between said iange and sleeve and said cap, and a second screw-threaded cap adapted to fit over Said sleeve and having an imperforate top and a disk of yielding material below said imperforate top, substantially as described.

5. An inking device for stamp-pads comprising a tube closed at one end and open at the other andadapted to contain a supply of ink, a perforated plate fitting within the open end of said tube, a felt material provided over said perforations, and a disk of pervious material fitting over said felt and having its edges gripped and held between `said plate and the walls of said tube, substantially as described.

In witness whereof I have hereunto set my hand, this 3d day of October, 1904, at Philadelphia, Pennsylvania.
